thanks for your patience!
okay, i will get a picture or sequence wich looks similar to that

lets take the red cube from the bottom for example, what i need is a plane version of the sides.
like this

this is needed to remap it on the same objects build in real per projection(the arrangment with the cubes). sounds strange but i try to get rid of a extra renderprosess where i do this step in the 3d software.
so slicing it in after effects and de-streching the shapes, like i thought a reversed corner pin workflow.
uiuiui
may sound like a bad strategy but its not i think.
thanks!
